I'm also seeing a similar problem - I have a cluster of high-volume mailservers delivering mail over nfs to maildirs on a netapp. The cluster was all 4-stable, but I decided to mix a couple of 5.1 boxes in to see how they would do. The 5.1 boxes accepted and queued mail as well as the 4-stable boxes, but delivering the mail into the maildirs over nfs, I kept seeing those short-lived hangs, and so the queues started to back up as the boxes were accepting mail faster than they could deliver it. My mounts are all nfsv3 over udp. -Jason -------------------------------------------------------------------------- Freud himself was a bit of a cold fish, and one cannot avoid the suspicion that he was insufficiently fondled when he was an infant. -- Ashley Montagu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) Comment: See https://private.idealab.com/public/jason/jason.gpg iD8DBQE/TYRhswXMWWtptckRAl7XAKDqAe2Z3HnT7bb+J6gPchMfxGo2fQCaA8u0 8wKNDwTh8NIFkLUNdi2HV2Q= =g19M -----END PGP SIGNATURE-----
